Stability is a fundamental premise for secure operation of every electric power system. As the loading demands are constantly increasing and the transmission networks are aging, the operating conditions of worldwide power systems have been pushed ever closer to their stability limits. Meanwhile, the integration of renewable energy sources has been constantly increasing. Particularly, Canada is a world leader in the production and use of all kinds of renewable energy. Although renewables bring numerous benefits, they also pose new challenges to power system stability. For example, the distinct dynamic responses of wind turbines and photovoltaic generators to disturbances may aggravate the contingencies, and thus deteriorate the stability of the overall power grid. As the penetration of renewables continues to increase in the foreseeable future, it is imperative to study the impacts of different renewables on various power system stability properties in order to enhance the stability and reliability of modern low carbon power systems. This research program intends to examine the impacts of the randomness of renewables on transient and voltage stability of electric power systems, which have not been well recognized and addressed. Indeed, the variability of renewables may affect the stability regions for transient stability and reduce the voltage stability margins. In addition, the proposed research program will develop analytical and computational tools to conduct stability analysis for the systems integrating renewables, and furthermore design control measures to enhance the stability of those systems. From the theoretical perspective, this research program will exploit concepts from advanced nonlinear system theory in the context of power systems, and extend the existing results by incorporating stochasticity and even produce novel theoretical results in their own rights. From the practical view point, the research outcomes will provide physical insights, quantitative measures and computational tools to system operators on evaluating and enhancing the stability of power systems integrating renewables in the real world. The research outcomes will advance seamless integration of renewable energy sources into power grids, which is advocated not only in Canada but also globally. The four graduate students to be trained in this program will be well-equipped to contribute to the future of the Canadian power industry. In particular, Quebec has developed a solid reputation on the world stage in hydro-electric development, and is now at the forefront of research on integrating significant amounts of wind power into its grid. In this regard, the goals of the research program comply with the interests of local industries, and the outcomes of this research program will generate various collaboration opportunities with industry partners in the near future.

稳定性是每个电力系统安全操作的基本前提。随着负载需求不断增加，传输网络正在老化，全球电力系统的运行条件已经越来越接近其稳定性限制。同时，可再生能源的整合不断增加。特别是，加拿大是各种可再生能源的生产和使用的世界领导者。尽管可再生能源带来了许多好处，但它们也为电力系统稳定带来了新的挑战。例如，风力涡轮机和光伏发电机对干扰的独特动态响应可能会加剧偶然性，从而恶化整体功率网格的稳定性。随着可再生能源的渗透在可预见的将来不断增加，必须研究不同可再生能源对各种电力系统稳定性属性的影响，以增强现代低碳电源系统的稳定性和可靠性。 该研究计划旨在研究可再生能源对电力系统瞬时和电压稳定性的随机性的影响，这些电力系统尚未得到很好的认可和解决。实际上，可再生能源的可变性可能会影响瞬态稳定性的稳定性区域，并降低电压稳定性边距。此外，拟议的研究计划将开发分析和计算工具，以对整合可再生能源的系统进行稳定性分析，并采取设计控制措施，以增强这些系统的稳定性。从理论的角度来看，该研究计划将在电力系统的背景下从先进的非线性系统理论中利用概念，并通过纳入随机性甚至在其自身权利中产生新颖的理论结果来扩展现有结果。从实际的角度来看，研究成果将为系统操作员提供物理见解，定量措施和计算工具，以评估和增强电力系统在现实世界中整合可再生能源的稳定性。研究结果将使可再生能源无缝整合到电网中，这不仅在加拿大而且在全球范围内提倡。在该计划中接受培训的四名研究生将有足够的能力为加拿大电力行业的未来做出贡献。尤其是，魁北克在水力发电开发的世界舞台上取得了良好的声誉，现在正处于将大量风能整合到其网格中的研究的最前沿。在这方面，研究计划的目标符合当地行业的利益，并且该研究计划的结果将在不久的将来与行业合作伙伴产生各种协作机会。
